The [[LBOUND]] function returns the smallest valid index (lower bound) of an array dimension.
|
||
|
|
||
|
|
||
|
{{PageSyntax}}
|
||
|
:{{Parameter|result%}} = [[LBOUND]]({{Parameter|arrayName}}[, {{Parameter|dimension%}}])
|
||
|
|
||
|
|
||
|
{{PageDescription}}
|
||
|
* {{Parameter|arrayName}} specifies the name of the array.
|
||
|
* {{Parameter|dimension%}} specifies the dimension number, starting with '''1''' for the first dimension.
|
||
|
** If omitted, {{Parameter|dimension%}} is assumed to be '''1'''.
|
||
|
** If {{Parameter|dimension%}} is less than '''1''' or is greater than the number of dimensions, a [[ERROR Codes|subscript out of range]] error occurs.
|
||
|
* [[LBOUND]] and [[UBOUND]] are used to determine the range of valid indexes of an array.
